Case History
A healthy, 10-year old Egyptian male presented to the orthodontic clinic with a chief complaint of the presence of two large front teeth. The medical history was not relevant.
Clinical Examination
Extra-oral examination revealed a symmetrical proportionate face and convex profile. (Figure 1) Intra-oral examination indicated the patient was in the mixed dentition stage with a Class I molar relationship, normal overjet and overbite, and rotated upper left central incisor (FDI 21). Teeth 21 and 22 were in cross bite, while tooth 12 had not yet erupted. The upper arch was U-shaped, while the lower jaw was parabolic.

The two abnormal incisors presented nothing of significance incisally. The crowns were similar in shape, but the left central incisor was slightly wider than the right central. There was a mid-line shift in the lower to the right. Teeth 63, 65, 85, 74, and 75 were restored. Oral hygiene was fair. (Figure 2. a, b, c, d)
